自锚式悬索桥缆-梁锚固系统方案设计

Design of cable-girder anchorage system scheme in self-anchored suspension bridge

本文根据已建以及待建自锚式悬索桥工程实例,将自锚式悬索桥工程中主缆在加劲梁梁端的锚固方案进行了总结分析,从施工方面、经济性以及美观性等方面指出了各种锚固方式的优缺点以及适应性。按照锚体材料的不同将现有锚固方式重新进行了分类,综合现有的分类方式提出了一套锚固系统方案设计流程。这种设计流程条理清楚、直观易理解,为今后的自锚式悬索桥主缆锚固系统设计提供指导,快速的形成锚固系统方案,提高设计效率,并获得更好的经济性和美观性。

According to the engineering examples of the self- anchored suspension bridges built and to be built,the cable- girder anchored projects are summarized and analyzed. From the construction,economy and aesthetics aspects,the advantages adaptability of various ways of anchoring and are pointed out. According to the different materials of the existing anchorage,the way of anchoring is re- classified and a set of anchor system design process is put forward based on the classification of the existing anchorage systems. This design process is clear,intuitive and easy to understand and can provide guidance for the design of self- anchored suspension bridge main cable anchorage system in the future. Using this design process,anchorage system scheme will be quickly put forward,the design efficiency can be improved and the bridge will be more economic and more beautiful.
